Moreover, the md5 code can only be submitted before 20 o'clock today, and then the corresponding file can only be submitted at 22 o'clock (the file cannot be modified at this time, and the md5 code will be incorrect and invalid once it is modified). I also took part in the competition this year and chose question B, what's more, there is a wrong mark in the abstract. Although there is no problem in the back, there are defects.
Mathematical modeling is to establish a mathematical model according to actual problems, solve the mathematical model, and then solve the actual problems according to the results.
When it is necessary to analyze and study a practical problem from a quantitative point of view, people should use mathematical symbols and language to establish a mathematical model on the basis of in-depth investigation, understanding of object information, making simplified assumptions and analyzing internal laws.
Mathematical technology:
Over the past half century, with the rapid development of computer technology, the application of mathematics has not only played an increasingly important role in engineering technology, natural science and other fields, but also penetrated into new fields such as economy, management, finance, biology, medicine, environment, geology, population and transportation with unprecedented breadth and depth. The so-called mathematical technology has become an important part of modern high technology.
